WILLIAM C. WREN, OF BROOKLYN, NEW YORK", ASSIGNOR TO GEORGE WREN, OFSAME PLACE.

HAND-TRUCK.

SPECIFICATION forming part of Letters Patent No. 292,609, dated January29, 1884.

Application filed November 30, 1883. (No model.)

To all whom, it may coltcern:

Be it known that I, \VILLIAM O. WREN, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented a new and useful Hand- 'Iruck, of which the followingis aspecification.

My invention relates to hand-trucks used for moving loads in stores, oron docks and other places; and the object of my invention isto produce acheap, durable, and indestructible handtruck for these purposes. Iattain these objects by the device illustrated in the accompanyingdrawings, in which Figure 1 is a side elevation of the truck. Fig. 2 isa side elevation of the frame or bail. Fig. 3 is a plan view of the bailor frame. Fig. 4 is a cross-section of a cross-bar, C, thimble B, andbail A.

Similar letters refer-to similar parts throughout the several views.

The parts marked A represent the bail, which, with the cross-bar O,sockets or thimbles B, nose-piece F, and wheel or pillowblocks D,together form the frame. These parts, as shown at Figs. 1, 2, and 3, ifmade of wrought-iron, are welded together, so as to form one piece; orif made of a cast metal are cast in one piece. I

The handles or side bars, M, for lightness,

are made otmetal tubing, and are inserted or driven through and into thethimbles B, attached to the sides of the bail A, as shown at Figs. 1 and4.

The wheel-guards E are also formed in one piece with the bail A, or theycan be separate and inserted between the bail and the handles M.

' The leg is made of aseparate piece of metal, and is attached to thethimbles B by a socket and bolt, as shown at L, Fig. 1.

The axle H, on which the wheel O turns, is placedunder the pillow-blockD, and is held to the pillow-block by a bolt and strap, as

shown at K, Fig. 1. i

The cross-barsO are made in the curved form shown at Fig. 4, to preventbarrels or round articles from rolling off the sides; and

also, when the bail is cast, to prevent the bail or frame from warpingby the unequal expansion of the different parts.

Having the bail or frames constructed as shown, with the nose F, sidepieces, A, thimblesB, wheel or pillow blocks D, and wheelguards E, allmade in and of one piece of metal, it is then heated to redness and thehandles M are driven into and through the thimbles B the whole length ofthe bail A until the ends reach the nose part F. If the inside diametersof the thimbles B are slightly smaller, or are the same as the outsidediameter of the tubular handles M, heating the bail -will enlarge them;and if the handles ,M, when cold,

are then forced 'or driven into the sockets the shrinkage of thethimbles will hold the bandles rigidly in the sockets under the bail A,thus forming a rigid indestructible truck.

It is a well-known fact that when trucks are made of wood and iron andjoined together by bolts or rivets, or when made of iron and mortisedand riveted, or bolted and riveted together, the parts at the mortise,rivet or bolt holes are weak and very soon rattle themselves to pieces.In my invention there is not onehole anywhere to weaken the frame, andneither bolts nor rivets to rattle loose.

What I claim as my invention is 1. A truck-frame composed of the sidesA, having sockets B for the insertion of handles, the cross-bars O, noseF, and wheel or pillow blocks D, all formed of one piece of -metal,substantially as shown and described.

2. In a hand-truck, the combination, with a frame, A, having'thethimbles B,'nose F, and wheel-block D, all of one piece of metal, of thetubular handles M, held in place by shrinkage of the thimbles,substantially as shown and described.

3. In a hand-truck, the leg L, in combination with a frame consisting ofthe sides A, nose F, cross-bars (3, wheel-block D, and sockets B, allsubstantially as shown and described.
